moreover,
u know how long Ksitigarbha has maintained the position of the Tenth Bhumni?!
"Buddha told Manjushri, "As an analogy, it is as if in the thousands of worlds, all the grasses, trees, bushes, straw, hemp, bamboo, reeds, mountains, stones, dust and every object is made into the Ganges River. And each grain of sand in the Ganges River becomes a great world. And each speck of dust in each world is compared to an aeon. And within those aeons the specks of dust that would accumulate would also become aeons. Increase this amount a thousand times and this is how long Ksitigarbha has maintained the position of the Tenth Ground - the highest ground or position that a Bodhisattva can reach! " 
..and it had not stated the other stages, it's already so long!!

And u know how many came to the preaching?
At that time, Buddha Sakyamuni asked Bodhisattva Manjushri, Mahasattva, "Do you know how many Buddhas, Bodhisattvas, heavenly beings, dragons, ghosts and gods from other lands and worlds are here in the Trayastrimsa Heaven for this instruction?" Manjushri answered, "World-Honored One, even using my divine power for thousands of aeons, I still would not be able to calculate how many are here." Buddha Sakyamuni said to Manjushri, "Even if I use my Buddha eye, I too cannot calculate them. These multitudes include all whom Bodhisattva Kishitigarbha has released, is releasing, and will release from suffering. That is, these multitudes include all living beings who live in the past, present and future!"wow, even Buddha eye also cannot calculate!!
